    SLN SLN 3d
    SLN three screw pumps are designed to avoid any pulsation, to ensure a smooth operation and to reduce to the lowest level the acoustic emissions, reducing all costs of second noise reduction measures. The pulsation-free flow of SLN pumps, allows Settima screw pumps also in output condition management critical to applications such as precision hydraulic controls and fuel metering.

    SLN pump can be equipped with a magnetic coupling if required.
